Justin Bieber's Mom, Pattie Mallette, Weighs in on Her Son's Behavior

Following a list of controversial antics during the last few months by her son, Justin Bieber, Pattie Mallette acknowledges the 19-year-old doesn't always do the right thing.

"I'm not naïve to think that my child is perfect and making all the best decisions of his life," the Nowhere But Up author, 38, recently said on Watch What Happens Live.

Bieber's recent controversial acts have included: writing that he hoped Anne Frank would have been a Belieber; collapsing on stage during a concert in London; appearing on stage at a show two hours after his scheduled performance time; and most recently, he was seen on video urinating into a mop bucket and yelling an expletive at a photo of former president Bill Clinton.

"He knows what I disagree with and he knows all the things that I'm really proud of him for, too," Mallete says. "I mean, people don't talk about all the great things he does every day. Every night before a show, he meets with Make-a-Wish kids. He goes to sick kids' hospitals. He visits with them [and] takes his time. He gives back to charities."

But Mallette fails to address anything specific about her son, vaguely telling ET Canada, "I just deal with whatever comes up, I think as you would if your kid was off to college and making decisions. You just … I just talk to him, I call him … and he knows what I think."

Mallette – who shot down Bieber questions by telling the reporter, "No one wants their mom on television talking about their business" – did say that when it comes to his relationship with off-and-on gal pal, Selena Gomez, she's "just [going to] support him in whatever he decides, and I think that he's made good decisions so far on that whole scene."
